Relisting Cartek 5X 243 majorly ported heads and cam combo. The heads were just sent to cartek for inspection June 2010. Only 1500miles since recent valve job, pressure checked and re-surfacing. The 5X cam was ground by Cartek to the heads at the same time. The heads have some inperfections on one of the combustion chambers from a prior piston giving out and putting some indentations but does not effect the performance of the head its all in the combustion chamber nothing on the head surface. I will also be including the correct length pushrods. Heads need valves springs of your choice and possibbly a cleaning other than that they are ready to run. The heads are set up for motors 4.060 bore and up and the cam was ground for a 427ci. No real dyno numbers with the setup because my bottom end was having issues but cartek has some 427's making 600rwhp with there 5X combo.
